Abstract

In the biological treatment of organic matter for the purpose of producing compost, soil amendments or bio-fuel it is known that in order to ensure aerobic conditions during the entire treatment process air has to be channeled through the organics to provide for a sufficient oxygen level and to remove excess heat. It is also known that during the bio-chemical breakdown of the cell-structure of the organics moisture is released, which has to be removed to prevent parts of the organics turning into an un-aerobic process stage. The present invention provides a means to aerate organic matter and to collect and remove liquid from organic matter via a specifically designed channel. The channel contains a pipe comprising multiple orifices for air distribution or removal. The top of the channel is closed with a removable perforated cover. One or more than one channel combined to a series form an aeration system. The channels of an aeration system are integrated into the floor of a bin-type reactor and connected via pipes to a manifold outside the reactor for air distribution or removal. These pipes are also connected to the liquid collection and removal system comprised of a pipe outside the reactor, which directs collected liquid to storage or treatment tanks. Airflow in the channels, pipes and manifold is maintained by an air distribution system comprised of an exhauster/blower and regulated by means of dampers or valves. All process air is exhausted via a biologically active filter material in a bio-filter bed for odor control purposes. All liquid is collected and processed.
